Title: Pressurised gas circuit breaker - includes sliding rods operating two sealed contact sets allowing independent access to each part of extinction chamber
Inventor: NICOLOSO DANTE
IPC: H01H33/56
Filed: 1981-10-12
Abstract: The device includes two extinguishing chambers in a V-formation for each phase. A control jack is situated at the base of the structure to transmit movement to the contacts in the two chambers. In the V-shaped joint there are two sealed guide tubes each containing pressurised gas. Each tube extends from a straight section in the common support to a curved section linking this section to one of the extinguishing chambers. A rod slides inside each tube with little friction, one end being attached to the operating jack, and one end being attached to the moving contact. Seals ensure that the tubes are isolated from each other and from the associated mechanism. With this arrangement it is possible to dismantle one extinguishing chamber without disturbing the other.

Inventor: HAMON CHRISTIAN
IPC: C07C1/20
Filed: 1982-01-04
Abstract: Production of unsaturated hydrocarbons of 2-5 carbon atoms from methanol in the presence of zeolitic catalysts is effected by introducing gaseous methanol into a carrier gas, the concentration of the methanol in the entering mixture being between 5 and 60% by volume, and passing the mixture through a catalytic bed based on synthetic mordenite of the so-called de-aluminized type whose Si/Al ratio (atomic) is higher than 80, the flow rate of the methanol being between 1 and 5 liters of liquid methanol per liter of catalyst and per hour. The reaction is carried out at a temperature between 350 DEG  and 550 DEG  C., under a pressure which can reach 20 bars. The de-aluminized synthetic mordenite is prepared by subjecting the mordenite to a series of alternate acid and hydrothermic treatments, the said series commencing with an acid treatment and terminating with an acid treatment.

Title: Ion exchanger with graft cellulose plates
Inventor: BOULLARD JACQUES
IPC: B01J47/12
Filed: 1982-11-04
Abstract: Appts. comprises a stack of graft cellulose plates oriented transversely to the flow path between inlet chamber and outlet chamber.  These plates alternate with header plates.  The header plates form, on one side, a distributor chamber connected to the inlet chamber and, on the opposite side, a collecting chamber connected with the outlet chamber.  The facing sides of two successive header plates thus constitute respectively the inlet or feed header chamber and the outlet collecting chamber for a stack of graft cellulose plates lying between them. Pref. the two faces of a header plate have a radial and hoop grooves acting as the header or collecting channels. Perforated plates cover these grooves so as to prevent the cellulose material passing into them and blocking them. These perforated plates may be of fine mesh material. As compared with a previous, similar arrangement, only one type of intermediate plate or header is required and blockage of the ducts when the cellulose expands is avoided.
